I think your palettes have gotten much more controlled since the start, I like the moods you've achieved on this one, this one and this one for example. I also like the palette and clear separation of the figure and background on this one. Good construction and pose on this figure! The hands could've used more definition though.
ah well.. there are problems in understanding whats going on in that snow pic i guess. apart from that it was fun to paint that future soldier dood..theres a more detailed version but this one has more clearity
